A Bulk Glassy Cu--Zr--Ti--Sn Alloy with Superior Plasticity

Hua Men and Tao Zhang

(Cu_0.5Zr_0.425Ti_0.075)₉₉Sn₁ bulk glassy alloy exhibited a large plastic strain to failure, about 8%, in uniaxial compression. High resolution transmission electron microscopy showed formation of nanocrystallites in the sample subjected to a plastic strain of about 3%. The large plasticity was attributed to the deformation-induced nanocrystalization in an amorphous phase.
